| static CoordinateFrame IS3D::DrawMgr::getRoomToVirtualSpaceFrame | ( | ) | [static] |
This is the transformation between RoomSpace and VirtualSpace. Initially, the two spaces are the same. As the user navigates around VirtualSpace changes, but RoomSpace stays fixed to the physical Cave, monitor, screen, trackers, etc.. This transformation is composed of two parts: 1. a uniform scale factor, 2. a rigid-body CoordinateFrame transformation.
| static double IS3D::DrawMgr::getRoomToVirtualSpaceScale | ( | ) | [static] |
| static void IS3D::DrawMgr::setRoomToVirtualSpaceFrame | ( | const CoordinateFrame & | roomToVirtual | ) | [static] |
Sets the rigid-body CoordinateFrame transformation between the Room and Virtual spaces.
| static void IS3D::DrawMgr::setRoomToVirtualSpaceScale | ( | const double | scale | ) | [static] |
Sets the uniform scale factor between tne Room and Virtual spaces. Increasing the RoomToVirtualSpaceScale has the effect of shrinking the virtual space w.r.t the Room - zooming out.
| static Vector3 IS3D::DrawMgr::roomPointToVirtualSpace | ( | const Vector3 & | v | ) | [static] |
Use these to convert from RoomSpace to VirtualSpace, applies a CoordinateFrame transformation as well as a scale.
| static Vector3 IS3D::DrawMgr::roomVectorToVirtualSpace | ( | const Vector3 & | v | ) | [static] |
| static Vector3 IS3D::DrawMgr::roomNormalToVirtualSpace | ( | const Vector3 & | v | ) | [static] |
| static Vector3 IS3D::DrawMgr::virtualPointToRoomSpace | ( | const Vector3 & | v | ) | [static] |
Use these to convert from VirtualSpace to RoomSpace, applies a CoordinateFrame transformation as well as a scale.
| static Vector3 IS3D::DrawMgr::virtualVectorToRoomSpace | ( | const Vector3 & | v | ) | [static] |
| static Vector3 IS3D::DrawMgr::virtualNormalToRoomSpace | ( | const Vector3 & | v | ) | [static] |

| static Vector2 IS3D::DrawMgr::screenPointToG3DCoords | ( | const Vector2 & | screenPt | ) | [static] |
Converts IS3D's screen space coordinates into G3D's coordinates, which are in pixels rather than floating point.
| static Vector2 IS3D::DrawMgr::roomSpacePointToScreenPoint | ( | const Vector3 & | roomPt | ) | [static] |
Projects a Room space point onto the filmplane, then returns it in Screen coordinates.
| static Vector3 IS3D::DrawMgr::screenPointToRoomSpacePoint | ( | const Vector2 & | v, | |
| bool & | hitGeometry | |||
| ) | [static] |
This converts a screenspace point, like the coordinates of the mouse to a 3D point by reading back the current Z-buffer to find the first piece of geometry that is intersected by the point on the screen. If there is no geometry at the location then the point returned will lie roughly on the far clipping plane and hitGeometry will be set to false.
| static Vector3 IS3D::DrawMgr::screenPointToRoomSpaceXYPlane | ( | const Vector2 & | v | ) | [static] |
This converts a screenspace point, like the coordinates of the mouse to a 3D point that lies in the RoomSpace XY plane (Z=0).
| static Vector3 IS3D::DrawMgr::screenPointToRoomSpaceZEqualsPlane | ( | const Vector2 & | v, | |
| double | z | |||
| ) | [static] |
This converts a screenspace point, like the coordinates of the mouse to a 3D point that lies in the RoomSpace plane Z=z.
| static Vector3 IS3D::DrawMgr::screenPointToRoomSpaceFilmplane | ( | const Vector2 & | v | ) | [static] |
This converts a screenspace point, like the coordinates of the mouse to a 3D point that lies in IS3DEngine's current notion of where the filmplane is in RoomSpace. By the way, the filmplane location and size will only change if you resize the rendering window.
| static Plane IS3D::DrawMgr::getFilmplane | ( | ) | [static] |
The filmplane, in projected VR, the same as the plane of the screen. Returned in RoomSpace coordinates.
